My Answer: a & c. But i saw in a previous post that the answer is b) also. Can a nested class extend the outer class?

This is the first question of the Barry Boone's test (i have a paper copy of this). I would appreciate if anybody could let me know where the answers for this test are. The only clue i have is that the previous link ended with JavaCert2.html.

class TestInner {
public static void main(String args[]) {
new TestInner().new TestInner2().printSomething();
new TestInner.TestStaticInner().printSomething();
}

void printSomething() {
System.out.println("TestInners print");
}

class TestInner2 extends TestInner {
void printSomething() {
System.out.println("Inner class print");
super.printSomething();
}

}

static class TestStaticInner extends TestInner {
void printSomething() {
System.out.println("Static inner print");
}

}

}
This code compiles and runs successfully on my 1.2 JVM so I guess you can extend an outer class in an inner class. But then I have to ask in what situation would one want to do this?

hey, i just got promoted to ranch hand, does that mean i'm certified now?
